Question

Factorize the following expression of z^2+6z+8

Answer 1

Step-by-step explanation:

z^2 + 2z + 4z + 8

z( z +2) + 4( z +2)

( z+2) (z +4)

z= -2 or z = -4

Answer 2

Answer:

=z = -2, z= -4

Step-by-step explanation:

p(x)=z^2+6z+8

=z^2+4z+2z+8

= z(z+4)+2(z+4)

=(z+2)(z+4)

=z= -2, z = -4

hope it is correct
